Abstract

Die Erfindung betrifft eine Füllstandanzeige (1) für den Füllstand eines Filterbeutels in einem Staubsauger mit einem Anzeigekolben (3), wobei der Anzeigekolben (3) durch die Druckdifferenz am Filterbeutel bewegbar ist, wobei weiter der Anzeigekolben (3) als Membrankolben (4) mit einer rollbaren Weichmembran (5) ausgebildet ist und einen Kolbenschaft (7) aufweist, der in eine Ruhestellung des Anzeigekolbens (3) vorgespannt ist. Um eine möglichst hohe Messgenauigkeit zu erreichen, schlägt die Erfindung vor, dass der Kolbenschaft (7) kippbeweglich gelagert ist und dass die Membran (5) den Anzeigekolben (3) zentriert.
